Using NASA's Chandra X-ray space telescope, astronomers have performed high-resolution X-ray spectroscopic observations of a bright low-mass X-ray binary known as GX 340+0. Results of the observational campaign, published ...
For the first time, new theoretical models, published in Astronomy & Astrophysics, connect the magnetism at the surface of long-dead stellar remnants (white dwarfs) with recent evidence of magnetism at the cores of their ...

The center of our galaxy is an extreme place. Surrounding the supermassive black hole Sagittarius A*, stars are packed densely into a region where gravity, radiation, and dark matter all interact in complex ways. It is a ...
The most realistic picture yet of how galaxies formed and then evolved from the beginning of time has been revealed in a suite of new and unique audiovisual simulations. These data, accepted for publication in the Monthly ...
